This design incorporates improvements by Dr. R. O. Brinkhurst, Institute of Ocean Sciences, specifically for obtaining quantitative samples of fast-moving Tubificidae.

Because the valve is locked open during descent, there is minimal frontal wave and minimal warning to fauna at the water/bottom interface. It is messenger-operated and is under your full control: you can keep the K-B® open until you are sure you have a sample. The heavy K-B® affords better penetration. Units are also available without carry cases.

Features

  • For deep water over 100 meters
  • For fauna at water/bottom interfaces
  • Can be free-dropped up to 10 m (33’)
  • In medium or heavy-duty versions
  • Unrestricted flow, little bottom disturbance
  • Messenger closing for more control
  • Parts interchangeable with Wildco® corers
